So what was it Dan? I can read. You said it idled like a "mild" cam, but a decent carb tuner can make a big cam idle like a kitten.
So it wasn't the cam was too big. Or too small. Could it be he didn't have the timing curve right? Or his idle circuit was garbage? Or maybe he had a HUGH idle feed restrictor in it? Or a really small idle air bleed.
It damn sure wasn't an intake issue Dan. I've been running single plane intakes on street engines since 1980. How many have YOU used and tuned to KNOW (using your words Dan) they don't work on street engines??
Can you not see your **** up yet? And here you are doubling down over and over and over on YOUR bad advice.
